Tidal currents near Merrimacport
From NOAA's current predictions for Newburyport, Merrimack River, 6.1 miles away. Slack is when the current turns and the water is calmest; flood runs in with the rising tide and ebb runs out with the falling tide. Times are the peak of each run, in knots. The flood runs toward the WNW (288°) and the ebb toward the E (98°). The strongest current this week is 1.8 knots.

Best fishing times at Merrimacport
The bite score (0 to 100) adds up what anglers watch most: moving water (a tide running harder than usual here scores higher), solunar periods (major periods of about two hours centred on the moon overhead or underfoot, minor periods of about an hour on moonrise and moonset), dawn and dusk light, and how close it is to the new or full moon. Best times are the stretches of the day scoring near that day's top.

About the tides at Merrimacport
Merrimacport gets two high tides and two low tides almost every day, and the two highs are close in height. Over the next month the water typically rises or falls about 6.6 ft between a high and the next low.
The biggest swings in this window come around Wednesday, October 28, when the day's range reaches 9.1 ft, and again around Sunday, October 11 (7.6 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Tuesday, October 20, with only 5.8 ft between the day's highest and lowest water.
The lowest tide of the month is -0.5 ft at 9:33 PM on Wednesday, October 28. There are 9 minus tides (lows below the chart's zero line) in this window: the best times for tide pools, clamming and walking the flats.
The highest predicted tide is 8.6 ft at 2:42 PM on Wednesday, October 28. Onshore wind or a storm can push the real water level above that.
This is a reference (harmonic) station: NOAA predicts its tides directly from years of measured water levels here, which makes it among the most reliable predictions on the coast.
